So I went to the doctor, and she doesn't know what's wrong with my head. Asked some questions, did some basic neurological tests and she just told me to keep an eye on it. She gave me some pills for the nausea and some Tramadol (yay, opiates) for the pain, but still haven't found the root of the problem. My head still hurts but It's a lot less thanks to the pills and I can keep my food down a lot more easily. My parents said they're gonna take me to a quick clinic this weekend when I visit them at home (They're driving me, I don't have a car) to get a second opinion, so let's see if I can get at least a hypothesis in these next few days.
